Xiaomi’s original Mi Max smartphone was incredibly successful for the company — it says it sold over 3 million units — and it’s hoping the Mi Max 2 can bring even more people into the fold. Spotted by TechCrunch, the Mi Max 2 was announced today at an event in Beijing. It comes with a massive 5,300mAh that Xiaomi says will last two full days of use, with over 18 hours of video playback or 21 hours of GPS use.

If those numbers hold up — and that’s a big if — the Mi Max 2 will truly be an impressive device. The rest of the specs for the phone look strong as well:

• 2.0GHz Snapdragon 625 processor
• Android 7.0 Nougat with MIUI 8
• 4GB RAM with either 64GB or 128GB storage 
• 12MP rear camera, 5MP front-facing camera
• Rear fingerprint sensor, USB-C port

Xiaomi also noted that you can recharge the Mi Max 2 to 68 percent in an hour, which is pretty impressive. And, thanks to the USB port, you can use it to charge other devices as well, which could come in handy in a pinch. The Xiaomi Mi Max 2 will go on sale in China on June 1st for around $247 for the 64GB, and $290 for the 128GB version.
